The problem with your analysis (aside from the fact that this is launch software) is that this game is targeting a far higher level of graphics quality to something you'd expect to see today at 1080p60. Current demo performance suggest that the game is locked down to 30fps, the implication of which is that the game can reach Xfps but goes back-and-forth between X and [something above 30fps]. The PS4 has the hardware to run Battlefield 3 on Ultra @ 1080p far higher than 60fps. All of this "Gen 8 games are going to be 1080p30" talk is foolish.
